F2 Dev Notes and US-4571 at City College San Francisco a Week Apart

 This week I spent some time tightening up the workflow for comparing F2 ionospheric data across different POTA outings. It turns out documentation really does matter. By writing things down, I’ve not only made the manual process clearer but also pushed the automated flow forward. With GPT-5’s help on documenting proton and electron flux plots, and my own notes on numeric F2 graphs along QSO paths, the project is steadily becoming easier to repeat and share. I put in a little bit of time working on being able to easily compare F2 data for different POTA outings this morning. It turns out documentation really does matter, so I've been focusing a bit more on it. I have a number of tools that allowed me to pull in F2 data quickly. This week I've been trying to spend time pulling them into an automated flow. As I've implemented this flow, I've discovered that I haven't taken the time to document the tools I've already built.  I asked GPT5 to document the solar prot...

GloTEC Ionosphere Data

 KO6BTY and I have been playing with ground and spaced based ionospheric data for the last couple of years. This week, we started looking at the NOAA experimental GloTEC project's data. It's really nice in that it has virtually complete global coverage. Also, it's very up to date. At the time of this writing, it's 16:11 UTC and the most up to date data is from 15:45 UTC. I've used ChatGPT o3-mini to update our data analysis code for the new, to us,  GloTEC format and we're starting to see really interesting results. Below are two videos of maps we've created. The first one is for the maximum height of the F2 layer, also known as hmF2, and important for 20 meter ham radio propagation. The data is from Tuesday evening, 2025/02/12 UTC. The second is of the critical frequency, aka foF2, (the maximum frequency radio signal that will bounce vertically from the F2 layer), for the same time period. You can see the  Equiqtorial Ionization Anomaly (EIA) very clearly ...
